Rinascita Necklace of Fending ★★★

Taken all the way down to base materials, one Rinascita Necklace of Fending is 2 crafting steps deep and needs 4 intermediates — Grade 7 Vitality Alkahest ×1, Ilmenite Ingot ×1, Ophiotauros Leather ×1 and 1 other — which resolve to 11 distinct raw materials totalling 24 units, plus 32 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,346 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 26 are burned by the intermediates, so the real crystal cost is 9 Fire Cluster, 8 Earth Crystal, 6 Wind Cluster and 3 other kinds.

The chain crosses four disciplines — Goldsmith to Lv 90, Alchemist to Lv 90, Blacksmith to Lv 90 and Leatherworker to Lv 88 — so no single class can finish it unaided.

6 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Ash Diatomite (10:00, 22:00), Ilmenite (8:00, 20:00) and 1 other. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Ophiotauros Leather has the widest use: 153 recipes call for it, spanning seven of the eight crafting classes.
